Die Erfindung bezieht sich auf einen als Schlitten ausgebildeten Prellbock, der zum Aufhalten von Eisenbahnfahrzeugen oder -zügen in Kopfgleisen dient. Gemäß der Erfindung wird die Bremswirkung des Prellbockes außer durch sein Eigengewicht auch durch die auf ihn auffahrenden Fahrzeugachsen erzeugt und überdies durch eine auf Keilflächen wirkende Federbremsgruppe in hohem MaßeThe invention relates to a buffer stop designed as a slide, which is used for Stopping railway vehicles or trains in head rails is used. According to the invention the braking effect of the buffer stop is generated not only by its own weight but also by the vehicle axles that hit it and, moreover, to a large extent by a spring brake group acting on wedge surfaces

Gleitende Prellböcke, die mit festen Auflaufzungen für die abzubremsenden Fahrzeuge versehen sind und auf den Fahrschienen gleiten können, sind bereits bekannt, desgleichen auch zur Vernichtung der lebendigen Kraft von Eisenbahnzügen dienende Pufferwagen mit Radbremsklötzen und unveränderlichem Gleitwiderstand und ferner gleitende Prellböcke, deren gleitende Reibung durch Fang-Sliding bumper stops with fixed contact tongues for the vehicles to be braked are provided and can slide on the rails, are already known, as well buffer wagons also used to destroy the vital force of railroad trains with wheel brake blocks and unchangeable sliding resistance and also sliding buffer stops, their sliding friction by catching

Endlich gibt es mitten im Fahrgleis anzuordnende Fangvorrichtungen, bei denen in einem Hemmschuh vereinigte wagerecht liegende Druckfederpuffer gegen eine festliegende Keilschiene drücken. Von all diesen Fangvorrichtungen unterscheidet sich der vor- o sleepers can be enlarged, which are taken along one after the other as track sleepers chained to the trestle when the trestle is driven away under the loaded rails. Finally there are safety devices to be arranged in the middle of the track, in which horizontally lying compression spring buffers, united in a drag shoe, press against a fixed wedge rail. The previous one differs from all of these safety gears.

o liegende Prellbock im wesentlichen dadurch, daß der Hauptwiderstand des Bockes unmittelbar an den mit Leitschienen versehenen Fahrschienen erzeugt wird, gegen deren Flanken Keilkopfzuganker unter Federdruck angespannt sind und beim Vorstoß des Prellbockes noch weiter selbsttätig angespannt werden. o lying buffer stop essentially in that the main resistance of the block is immediate is generated on the rails provided with guide rails, against their flanks Wedge-head tie rods are tensioned under spring pressure and when the buffer stop is pushed forward can be tightened even further.

Der Prellbock ist auf einem in der Verlängerung der Fahrschienen liegenden oder damit zusammenhängenden Gleis verschiebbar und besteht aus zwei durch eine Pufferbohle A verbundenen Stehwänden B, deren sohlenartige Grundplatten C in lange Auffahrzungen C₁ auslaufen (Fig. 1 und 3 bis 6). Beim Auffahren eines Fahrzeuges oder Zuges steigen eine oder mehrere Achsen auf diese Zungen, worauf nach Anprall der Puffer der Bock so lange auf dem Gleise fortgleitet, bis erThe buffer is displaceable on a lying in the extension of the rails, or associated track and consists of two connected by a buffer beam A standing walls B whose sole-like base plates C in long Auffahrzungen C ₁ run (Figs. 1 and 3 to 6). When a vehicle or train drives up, one or more axles climb onto these tongues, whereupon after the impact of the buffer, the trestle slides on the track until it does

has destroyed the living force acting on him through his braking effect. Each block wall B can load two or four rails lying next to one another (including the running rail D) with its sole C (FIGS. 4 to 6, io and ii). The opposite flanks E1, E1, E2, E2 of the rail heads of a pair of rails are beveled at an angle (e.g. 15 °) from the vertical, thus forming a downwardly wider keyway E (Fig. 2 and 8) Longitudinal walls z. B. where the buffer stop is at rest, run parallel, while they are conically narrowed in their longitudinal direction on the parts of the braking distance in front of it, otherwise they can be narrowed or expanded as required (Fig. 2 and 8). The buffer stop is held in place by the wedge-shaped heads F of the bolts G entering between the pairs of rails, which are under spring pressure and can be tensioned as required and which, depending on the narrowing or widening of the groove E leading to their wedge heads, relax or tighten as the block slides away, so that this means that every required variability of the braking effect can be met over a certain braking distance. FIGS. 2 to 6 show the pairs of brake rails in a single arrangement, and FIGS. 8 to 12 in a double arrangement. As shown in FIG. 7, the drive-on tongue C2, located here in the groove, can be slidably connected to the brake slide for the purpose of gradually increasing the braking effect and relocated on the slightly rising sliding surface of the bearing blocks / (FIGS. 9 and 10), so that it is at increasing displacement lifts the locomotive and tender wheels one after the other. The sole C clamps the outer rail heads against the pressure of the wedge screws (Fig. 5, 6 and 11). In order to increase the resistance of the buffer stop, additional brake blocks acting as brake slides can be clamped behind it at suitable intervals on the slide in the same way as the block itself (FIGS. 7 and 12). These brake blocks consist of plates H, which, like the soles C of the main slide, encompass the rail heads, as well as the spring-loaded wedge head bolts F, G, whose friction surfaces grind against the inclined rail flanks E1, E2. The braking effect of the slide-like 5: bumper block is generated:

1. caused by the dead weight of the trestle between the sole and the running rail Friction;

2. by the friction between the tongue and the pad, as a result of the stress caused by the accrued Vehicles (Figs. 1, 3, 7 and 9);

3. by the friction of the wedges F clamped between the rail heads E ₁ , E ₂ , which lower a 6; Generate right wedge surface pressure, which increases from the initial position of the bracket due to the narrowing of the keyway E on a shorter path (Fig. 2 and 8).

Ρλτεν τ-An SPRU c H:

Sliding buffer stop with run-up rail for railway vehicles, which is connected to the 7; NEN guide rails is clamped, characterized in that the anchor bolts (G) with their wedge-shaped heads (F) engage in keyways (E) formed by the guide rails, which have a varying width to increase or decrease the braking force.
